LABOR leadership candidate Bill Shorten on Wednesday declared himself a man of the centre, insisting he was best-placed to appeal to the broader public over left-wing rival Anthony Albanese.

But the bid to point out his rival's hard left background came as Mr Albanese's blitz continued at a Brisbane campaign event on Wednesday night - with the backing of former Labor MP and Right faction member Arch Bevis.

Another Right member and former Gillard backer Craig Emerson has also backed Mr Albanese as well as Greg Combet, Tanya Plibersek, Penny Wong and Doug Cameron.

Mr Shorten's public endorsements have included former union boss Bill Kelty and former Labor ministers Richard Marles and Mark Dreyfus but right-wing unions are mobilising and it is understood more endorsements will be rolled out in coming days.

NSW Labor MP Ed Husic, a Rudd backer, on Wednesday joined Mr Shorten's team, saying he would bring a "fresh'' outlook to the role.

"I think he'll be someone that will definitely take our party forward,'' he said.

Mr Shorten, a member of the Right, continued his campaign on Wednesday, visiting a Melbourne women's centre to attack the lack of women in Prime Minister Tony Abbott's cabinet.

Environment Minister Greg Hunt brings his young daughter to the desk as he takes his oath, while Parliamentary Secretary to the Minister for education Scott Ryan draws attention with a very large and ornate bible.

The leader will be announced on October 13 after ALP members and the parliamentary caucus have voted, with each group worth 50 per cent to the final outcome.

Mr Albanese is expected to have the edge with rank and file members while Mr Shorten is believed to be slightly ahead in the caucus.
